# CustomFontRegistry.Merge Method 
 
Adds every font from another [FontRegistry](https://www.graphicsmill.com/docs/gm/T_Aurigma_GraphicsMill_Drawing_FontRegistry.htm.md) into this registry. This is much faster than re-adding the same fonts via [Add(String)](https://www.graphicsmill.com/docs/gm/M_Aurigma_GraphicsMill_Drawing_CustomFontRegistry_Add_1_bb3a7a4f.htm.md), since it reuses the source registry's already-parsed font data instead of re-parsing the font files.
